You love soft-serve ice cream. In the afternoons during the week at your high-paying

job in mid-town Manhattan, you frequently find yourself in line for Mr. Softee (see picture)

paying $4 for a vanilla cone with rainbow sprinkles. In order to save some money on rent and

other living expenses, you decide to move from mid-town out to Park Slope, Brooklyn, and are

surprised to find that Mr. Softee trucks sell the same vanilla cone with rainbow sprinkles for only

$2.5 in your new neighborhood. When you mention this to a friend, they tell you that ice cream

costs more in mid-town because the vending license to operate in Manhattan is significantly

more expensive.
